Front Panel Controls and Indicators
Enable: A push button used to turn the amplifier
on and off.
Level: A rotary control for each channel with
31 detents used to control the output level.
T he Macro-Tech 2402 amplifier delivers superior sonic accuracy and enormous amounts of power
®
from a low-profile design—perfect for touring and fixed installations. Crown's patented ODEP
(Output Device Emulation Protection) and Grounded Bridge™ output circuitry enhance reliability
and virtually eliminate distortion. Dual, Bridge-Mono or Parallel-Mono modes allow you to optimize
®
power to your loads, while IOC
tion meter, giving proof of distortion-free performance.
Enable LED: This amber indicator shows the on/off
status of the low-voltage power supply.
Signal/IOC: Each channel has a green indicator
that flashes to show amplifier output. If a channel's
output waveform differs from its input by 0.05% or
more, the indicator flashes brightly to show distor-
tion. This function provides proof of distortion-free
performance. In Parallel-Mono mode, the Channel
2 light stays on.
ODEP: Each channel has an amber indicator that
shows thermal-dynamic energy reserve. Normally,
each ODEP indicator is lit to show available reserve
energy. In the rare event that a channel has no
reserve, its indicator will dim in proportion to ODEP
limiting. An ODEP indicator may also turn off under
other conditions.
Back Panel Controls and Connectors
Stereo/Mono: A three-position back panel switch
used to select Stereo, Bridge-Mono or Parallel-
Mono mode.
Reset: A push button for each channel, used to
reset the circuit breaker that protects each power
supply.
Input Ground Lift: This switch on the PIP2-FXQ is
used to isolate input signal grounds from chassis
ground to prevent ground loops.
Sensitivity: A three-position switch inside the
PIP™ compartment used to select the input sensi-
tivity for both channels: 0.775 volts or 1.4 volts for
standard 1 kHz power, or a 26 dB voltage gain.
Input Connectors: Factory-installed PIP2-FXQ
provides one 3-pin female XLR connector for each
channel in parallel with one balanced 1/4-inch
phone jack connector for each channel.
Output Connectors: Two sets of color-coded bind-
ing posts for banana plugs, spade lugs or bare wire
(European models do not accept banana plugs).
(Input/Output Comparator) circuitry acts as a supersensitive distor-
Protection
Macro-Tech amplifiers are protected against shorted,
open or mismatched loads; overloaded power sup-
plies; excessive temperature, chain destruction phe-
nomena, input overload damage and high-frequency
blowups. They also protect loudspeakers from input/
output DC and turn-on/turn-off transients.
Cooling
Flow-through ventilation from front to side panels.
Internal heat sinks with forced-air cooling for rapid,
uniform heat dissipation.
Dimensions
EIA Standard 19-inch (48.3-cm) rack mount width
(EIA RS-310-B), 3.5-inch (8.9-cm) height and 16-
inch (40.6-cm) depth behind the mounting surface.
Weight
Net Weight: 51 lbs. 12 oz. (23.5 kg).
Shipping Weight: 65 lbs. (29.5 kg).
Accessories
Cooling fan option, level control shaft lock.
Crown PIP and PIP2 modules which allow net-
working via HiQnet or TCP/IQ.
Regulatory Certifications
Other Applications
Note: All measurements apply to units in Stereo mode
with 8-ohm loads and rated input sensitivity unless
otherwise specified.
